Summary
👤
Senior🎓
Top SchoolJefferson Silveira is a Senior Software Engineer with over a decade of experience building and rescuing backend systems, data platforms, and APIs across greenfield and legacy environments. He recently architected and implemented a TV viewership analytics pipeline at BENlabs—owning data modeling, Nielsen/Gracenote ingestion into Snowflake, demographic calculations, and a replacement API that retired a long-planned legacy platform. Comfortable as both an individual contributor and a distributed team lead, he has driven TypeScript rollouts, reversible infra changes, and mentoring programs that produced promotions and smoother delivery. He pairs strong operational instincts (revived New Relic visibility, migrated 70K+ files during S3 modernization) with product-facing work, shipping monitoring tools and full-stack internal apps. An early open-source author, he wrote the first LibreSign Nextcloud app that grew to widespread adoption, showing his knack for practical, standards-compliant engineering. Based in Portugal and fluent in English and Portuguese, he thrives on untangling unfamiliar systems and turning them into reliable, auditable platforms.
